Be it known thatl, Gnome W, Emncn, a citizen of the United States, andresiding at Brooklyn, in the county of Kings and State of New York,,haveinvented certain newand usefullmprovemente in Machines for MakingArmored Cable and the like, of which the following is a specification,

will enable those skilled in the art to which it appertains to make anduse the Home.

This invention relates to machines for limiting nrn'iored cables andwhat in com monly known as flexible metallic (itilltllliifi for cables.and the object of the invention in to make the operation of suchmachines: more practical, eilicient and economicah and the imcntiondescribed and claimed herein relates particularly to the provision of anautomatic stop device for machines of the class and for the purposespecified, and the object of whichis to automatically stop the machine,in the event of the twisting or snarling of the material employed. topre vent the, breaking' of such material when twisted or snarled, whichcommonly occurs in the operation of machines of the (flaw; specified,and which breakage causes concider-able waste in the production and byreason of which consider-aide time and lnhor is also required in orderto again start the. machine after such break.

My improved automatic stopfor machines of the class specified will. inthe event of a twist orisnarl in the materialemployed, be

automatically operated to disengage the will means for driving thenihcliine and actuate devices to apply a brake to the ro-- tnry memberusually employed in machines of-thc CltlSS'SPQClfiHL and said mac-luneor the rotary member thereof will be stopped in time to preventthehrieaking of the moterial twisted or snarled as above set out,

"ling the twist or sniirl, which operation taes but u few minutes, themuchine. may be again put into operation by means of the lever usuallyemployed for this and by upsn The furious details' of'my improvementwillbe folly disclosed in the following epoch ficntion, of whichtheaccompanying drawsuch I too construction bro en away and in section;

Secured to the shaft 21 is a pulley 22' ill'Hi n similar pulley 23 isrotatnbly mounted on -nid shaft and u belt 24 is adapted to oper etc inconnection with the pulleys '32 and '2 in drive the machine in thelinllfll manner and the u-uul bolt Hhlft lever its: is pivoted to thel'ronumember 14 in the-usual manner. Secured to the shaft 21 between thepinion '20 and pulley 22. is a sprocket wheel 26 in connection withwhich a chain 27 operates, which also operhtes in connection with alarger proc-kct wheel 28i around which the formed The sprocket wheel.28is mounted on one end portionof a. mandrel; 29 which passes through thetubular shaft 17 and through the rotar member 18,; and the other endportion the extensionBO. The construction and operation of the mandrelis-the same as that usually employed in machines of the class specifiedand for this reason further description of the details thereof will notbe .given.

The belt shift 25 is pivoted to a longitudinally movable rod 31 as shownat 32. The rod 31 is mounted in suitable bearings 33 and 34, and anoperating lever 35 pivoted to a suitable frame member as shown at 36 ispivotally connected with the rod 31 as shown at 37. The lever 35, therod 31 and the belt shift 25 and the various parts connected therewithand in connection with which said parts operate is the same as thatusuallyemployed in connection with machines of the class specified.

In Figs. 1 and 4 of thedrawing, I have indicated at 38 bracketssupported by the framework of the machine and in which are mounted ashaft 39 with the central portion of which is connected a grooved wheel40 roduct 41 passes, 'and from this grooved wlieel said product passesout through the machine in the usual manner. In Fig. 1, 42 indicates thesizing rollers usuall Y employed in machines of the class specified, thefunction 01 which is to grip the-formed product 41 and prevent thetwisting of the same in the operation of the mandrel as well as tocompress said product to equalize the outer diameter thereof.

The rotary member 18 in the construction shown is in the form of afly-wheel, the periphery of which is enlarged or flanged as shown at 43,and .rotatably mounted on one W arms 51 between which therebetween, 85

face of said fly-wheel or rotary member are i the usual metal carryingspools or reels 44, two of which are shown. and on which is wound metal45, in strip or ribbon form. The face of the fiy-wheel is provided onopposite sides of the hub portion 46 thereof, and at right angles to thespools or reels 44, with beveled portions 47 mounted plates adapted tosupport rotary die members 48 and 49 of the usual or any preferred formof construction and guide rollers 50 are also mounted The rotary diemembers 48 and49 operate to suitablyshape or fashion the strip of metal45 as it passes usual manner.

Connected with the beveled portions 47 and the plates mounted thereonare. spaced the' metal 45 from the spools or reels 44 passes, said armsbeing adapted to straighten the metal-as as hereinafter described. The

various parts of the machine indicated .by

roof is provided with a tubular sition shown in Fig. 6. position shownin Fig. 8, are adapted to opon which are on said plates.

therebetween in thh' T tions 73 and weights it passes The metal 45 afterit passes through the arms 51 is passed ar und rotatably mounted arms 58pivoted to W, fly-wheel at 54 and springs 55 are connected with saidarms, and with said fly-wheel. and Serve to hold said arms in thepositions shown in Fig. 2. The arms 53 are. provided with extensions 56with which are connected fingers 57 adapted to operate in elongatedslots :38 of ram members 59 rotatably mounted on shafts 60 mounted inbearings 61 connected with the fly-wheel 18.

The cam members 5.! are arc-shaped faces and in Figs. (3 and 7 of thedrawing the (lotails of one of the cam members 59 and the partsconnected therewith and operating in connection therewith are clearlyshown. it being understood that the other cam member and parts areprecisely the same.

The cam members 59, or the faces .62 and 63 thereof, are adapted tooperate in connec tion with arms 64 pivoted to the opposite side of thefiy-wheel 18 as shown at 65 and springs 64" are connected with said armsand said fly-wheel, and normally serve to hold the arms in the positionshown in Fig. 6. The arms 64 when in the dotted line poand in the fullline grooved rollers 52 provided with erate in connection with a similarbut longer arm 66 hinged or pivoted to the frame member 13 as shown at(f7, and the frcecnd portion of the arm 66 is curved as shown at 68, andthe arms 64d 61' ,thet'rce end' portions thereof, are also curved as"shown at (it), whereby when either iof the arms 64 strikes them-ms (56the same will freely'pass there over as will be readily understoorh Alever 70 is pivotully connected with a bracket 71 connected with the topportion of the frame member 13 at one side of the machine as shown at72ft Ol'l" I1(l'fp)J'tl0I1 of said lever is provided in the top facethereof with a plurality ofteeth or projec- 74 are adapted to beadjnstably mounted on said end portion as clearly shown.. in Fig. 3, andthe othei end prtiog of said dlierils ifprkedkas shown at n in i 4,.an.31 I'm ted in said forked .eiid portion. I v

The bracket 71 is provided with an enlarged head portion 77 throughwhich the :he end portion 0D (i2 and with a Hat faces 63,

first named end portion of the lever 70 passes, and pivoted centrally ofsaidend portion of the lever is a link member 78, the free end portionof which is pivotally con nected with one end portion of a lever 79shown at 80. said lever 75) being pivoted at 81 to a bracket secured tothe frame meniher 13, as clearly shown in Figs. i and 3,

on the opposite sides of the frame member 13 are angle-iron members 87centrally of t which is mounted a shaft 88 on one end portion of whichis mounted an arm 89, and in the end of which is pivoted a rod 90 whichA is connected with the rod 76 by means of a turnbuckle 91.. as clearlyshown in Fig. 3. The other end portion of the shaft 88 is provided withan arm in the end portion of which is adjustahly mounted a bolt or screw93.

i A brake men'iber 94 is mounted to operate.

in connection with the bottom portion of the fly-wheel aiidconipt'ises aface portion 95,

preferably composed of fibrous material. and all arc-shaped back portion96, the opposite end portions of which are provided With cars 97 and 98.A link 99! is pivotml to the ears 9? as shown at 1 and to one of theangle-iron members 87 as shownat 101, and another link 109 is pivoted tothe cars 98 at 103 and to said angleiron member F47 as shown at 104 and.aSjVill be noted. the links 99 and 102 are adapted to aid in supportingl the brake member 9-1. as clearly shown in Fig; 2.

(entrally of the back portion 96 of the brake member at is a downwardlydirected member 1% in connection with which the screw or bolt 93operates as hereinafter described.

The operation of my improvement will be readily understoial by all thoseskilled in the art. on a careful consideration of the drawing. in viewof the foregoing specification. and the following statement. The methodof starting the machine, which includes the threading of the metal 45from the spools or reels 44 between the rollers 51 and then between therota'izy die members 48 and 49 and onto the mandrel is accomplished inthe usual manner, and in the operation of the machine said metal iswound onto an insulated wire cable 106 as indicated in Fig. 4. afterwhich the wound cable passes through the sizing rollers 42 and over andaround the grooved wheel 40, and out through the machine in the usualmanner.

In the practice of my invention the metal into 45 after it passesbetween the arms .31 is missed around the grooved rollers 5'. connectedwith the arms 53 and then passes between the die members in and 4S), andwhen the machine is in operation the various parts of my improvementwill assume the )osition shown in Figs. 1. '2. and 4 and the :ull lineposition in Figs. 6 and 8.

Should the metal become snarled in one of the spools or reels 44 theunreeling of the metal from said spool or reel is )revented, in whichoperation the grooved roller over which the metal snarled or in ldagainst unreeling passes is moved inwardly or radially into a positionapproximately similar to that shown at the left side of the 1 wvheel asshown in Fig. 8. In the 'above operation of the roller 52. the arm isswung on its pivot 54 against the tension spring 55 and the finger 57secured to the free end of the arm 53 "operates to move the cam member59' the position-sl'iown indotted lines in Fig; 7 which operation movesthe arm (34 into the position indicated in dotted lines in I igs. i3 andT and in full lines in Fig.

The movement of the arm 4 into the dot ted line. position shown in Fig.6 and into the full line position shown in Fig. 8. will bring the samein the path of the arm 66 in. the rotation of therotary member orflywheel 13, and when said arm 64 reaches the position shown in Fig. 8the arm 66 will be moved into the osition shown in Fig. 8 by the arm 64striking the same.

The movement of the arm 66 caused by the arm 64 striking the same movesthe link 78 into position to bring'the pivotal connection of said linkwith the lever 79 beyond a dead, center, after which the lever 70 willmove' from the position shown in Figs. 1 and '2 into the position shownin Figs. 3 and 8 by reason of the weights 74 at one end portion of saidlever 70. i The above movement of the lever 70 into the position shownin Fig. 3 will move the arm 99 upwardly into the position shown in Figs.3 and 8 by reason of the connection of said arm with the lever 70through the rods 76. fit) and turnbuckle 91. The upward movement of theany 89 oscillates the shaft RR which operation correspondingly moves thearm 92. which will move the brake member 94 into operative connectionwith the face or flangeportion 43 of the fly-wheel 18 as shown in Figs.3 and 8 by reason of the screw or bolt 93 engaging the projecting member105:

Th above operation of applying or moving the brake member 94 intooperative position by reason of the movement oflthe arm 53 or groovedroller mounted thereon over which the snarled metal passes also operatesto move the bcit '24 from the pulley 22 which is scured to the shaft 21onto the pulley 23..which is rotatably mounted thereon, or

into the position shown in Fig. 8. this operation being accomplisheal byreason of the connection of the lever 79 with the rod 31 as will bereadily understood.

The abov operation of shutting off the power and applying the brakemember 5 will stop the rotary member or fly-wheel 18 with in two r threerevolutions after the narling oeeurs. and in this way the breaking ofthe snarled metal is n'evented as will be readily understood. and whenthe snarl is straightened out. the machine is again put in operation bysimply manipulating the lever 35 to move the roll 31 with the belt shift25 and lever 79 connected therewith into the position shown in Fig. 1 inwhich operation the finger 57 on the end of the arm 53. previously movedinto the position shown in F ig. 8 is again returned into the positionshown in Fig. 2, or within the elongated slot in the cam member 59., andthe. brake member 94 is again moved into its inoperative position asshown in Fig. 2, as will be readily understood.
